John Martin Posted January 30, 2008 Share Posted January 30, 2008 Just yesterday a weird phenomenon happened. I was showing my little brother how to forge weld a chain link. I brought it up to a bright yellow heat, wire brushed it and then put flux on it. Put it back into forge. When I brought it out to weld, it was fine or so I thought. As I blew the first light hammer blow, might of a been a bit to hard, but still, the thing sent out a mini shock wave of flame and and made a really, really loud pop or boom noise. This scared him into going inside for the night. Does any one know what happened? Quote Link to comment Share on other sites More sharing options...
Shane Stegmeier Posted January 30, 2008 Share Posted January 30, 2008 You got a good forge weld... I used to get a nice gunshot report when I forgewelded quite often, (sadly not so often anymore;-) I would guess it is the metal sealing all the way around the edges of the weld, while there is still flux inside, and then having the flux Forcibly expelled. BUt that is just a dumb guess on my part. I like it when it welds like a gun shot, generally I KNOW I got a good weld when that happens... I like to hit it once or twice more after the POP and then put it back into the fire and reheat it to welding heat, and then reduce the weld to the finished size. Works for me;-) Quote Link to comment Share on other sites More sharing options...
easilyconfused Posted January 30, 2008 Share Posted January 30, 2008 Would that be related to the scarfing then? I've never heard that but I try to make sure that I have the scarfs formed to the edges don't contact first, allowing the flux and such to be forced out from the center.

ThomasPowers Posted January 30, 2008 Share Posted January 30, 2008 I get a pop when the flux is quite hot and "boiling" and then hit it with the hammer---just like the water on the hammer or anvil trick it gets compressed; builds up pressure and *pop*! Happens at a good temp for welding so usually means you'd get the weld as well. Quote Link to comment Share on other sites More sharing options...
John Martin Posted January 30, 2008 Author Share Posted January 30, 2008 Okay, thanks. Didn't know what had happened, guess i just got a good weld. Quote Link to comment Share on other sites More sharing options...
easilyconfused Posted January 30, 2008 Share Posted January 30, 2008 Ah, I guess I'm just going deaf or never paid attention then. I blame the ringing of the anvil :rolleyes: Quote Link to comment Share on other sites More sharing options...
Ecart Posted January 30, 2008 Share Posted January 30, 2008 I posted a thread somewhere on here about a time when I had water on my anvil. It popped the way Thomas Powers said. I am a Veteran and I get a little jumpy now and then so the pop nearly sent me into hiding So yeah, it scared the . . . um . . . stuffin' out of me.

John Martin Posted January 30, 2008 Author Share Posted January 30, 2008 He screamed like my little sister ran into the garage and then came back out when I kept saying something messed up that's all. "It scared the . . . um . . . stuffin' out of him to" lol. But I do have to admit he's 9, but still it would have been something to put on youtube. "Forge Welding" As I forge weld it, and little boom happens, a shockwave of flames, and my little brother screaming like something happened to him. Don't think blacksmithing would look so inviting after that. Quote Link to comment Share on other sites More sharing options...

How many of us love that sort of stuff? ;) Quote Link to comment Share on other sites More sharing options...
